Solution

The correct option is D 10
10 base pairs are present in each full turn of the DNA double helix.
The bases are nearly perpendicular to the helix axis, and adjacent bases are separated by 3.4 . The helical structure repeats every 34 , so there are 10 bases (= 34 per repeat/3.4 per base) per turn of helix. There is a rotation of 36 degrees per base (360 degrees per full turn/10 bases per turn).
